Mutational analysis of the PMS2 gene in sporadic endometrial cancers with microsatellite instability.

Erratum in

  • Gynecol Oncol 2001 Jan;80(1):109.



Approximately 20% of endometrial tumors have a defect in DNA mismatch repair and exhibit microsatellite instability (MSI). We assessed the role of the PMS2 DNA mismatch repair gene in MSI-positive sporadic endometrial tumors.


We examined 40 sporadic endometrial tumor specimens with MSI. All 15 exons of the PMS2 gene were investigated for sequence alterations by single-strand conformational variant analysis.


Twelve polymorphisms were identified, 8 of which were in the coding sequence. Four specimens revealed mutations in intronic sequences that are not predicted to affect the PMS2 mRNA. No mutations were detected within the coding region of the PMS2 gene.


We conclude that structural mutations in the PMS2 gene are not responsible for defective DNA mismatch repair in sporadic endometrial cancers with MSI. The identification of single nucleotide polymorphisms in the PMS2 locus may aid in the mapping and characterization of genetic diseases.
